Audio fruit turns into an important indicator of ride comfort.
Utility model content
For in the prior art the defects of, the utility model provide a kind of damping glue for auto sound, can reduce
In-car noise, improve riding comfort.
Damping glue provided by the utility model for auto sound, including be sequentially overlapped：Adhered layer, the first damping
Layer, fiber braiding layer, the second damping layer and protective layer, the outer surface of the protective layer are provided with depressed part and/or lug boss, are formed
Rough outer surface.
According to an embodiment provided by the utility model, gum paster is additionally provided with the inside of the adhered layer.
According to an embodiment provided by the utility model, the protective layer is aluminum foil plate.
According to an embodiment provided by the utility model, the surface of the aluminum foil plate is provided with embossing, and the embossing is formed
Rough surface.
According to an embodiment provided by the utility model, the integral thickness of damping glue is more than or equal to 2 millimeters.
According to an embodiment provided by the utility model, first damping layer and the second damping layer are that butyl is compound
Material.
According to an embodiment provided by the utility model, also set between first damping layer and second damping layer
There is porous noise reduction layer.
The operation principle of damping glue provided by the utility model for auto sound is as follows：Resistance provided by the utility model
Buddhist nun's glue can be pasted onto the inner side of plates of automobile by adhered layer, and the first damping layer is used to change the overall intrinsic frequency of metal plate,
So as to reduce the vibrations of metal plate, noise is reduced；After noise after the first damping layer damping reaches the second damping layer, in the second resistance
Further decay noise reduction in the presence of Buddhist nun's layer；Wherein, fiber braiding layer is provided between the first damping layer and the second damping layer, is passed through
Fiber improves the overall tensile strength of damping glue, avoids damping layer from ftractureing；Protective layer is posted on the outside of second damping layer, for protecting
The damping glue of inner side is protected, avoids damping glue from being damaged, meanwhile, the outer surface of protective layer is rough structure, when in-car sound
After ripple travels to the surface of protective layer, scatter, the sound wave of scattering crosses one another, and causes mutual consumed energy, causes to scatter
Sound be unable to reach the energy of echo, the reflex for weakening sound is also just played, so as to reduce to the anti-of the noise of in-car
Penetrate.Therefore, the damping glue provided by the utility model for auto sound can reduce in-car noise, improve riding comfort.

Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
It should be noted that unless otherwise indicated, technical term or scientific terminology used in this application should be this reality
The ordinary meaning understood with new one of ordinary skill in the art.
Embodiment one
The damping glue for auto sound that the present embodiment provides, including be sequentially overlapped：Adhered layer 2, the first damping layer
3rd, fiber braiding layer 4, the second damping layer 5 and protective layer 6, the outer surface of protective layer 6 are provided with depressed part and lug boss, are formed concavo-convex
Uneven outer surface.
The damping glue that the present embodiment provides can be pasted onto the inner side of plates of automobile 7, the first damping layer 3 by adhered layer 2
The intrinsic frequency overall for changing metal plate 7, so as to reduce the vibrations of metal plate 7, reduce noise；After the damping of the first damping layer 3
Noise reach the second damping layer 5 after, in the presence of the second damping layer 5 further decay noise reduction；Wherein, the first damping layer 3
And second be provided with fiber braiding layer 4 between damping layer 5, the overall tensile strength of damping glue is improved by fiber, avoids damping layer
Cracking；Protective layer 6 is posted in the outside of second damping layer 5, for protecting the damping glue of inner side, avoids damping glue from being damaged, meanwhile,
The outer surface of protective layer 6 is rough structure, behind surface of the in-car Acoustic Wave Propagation to protective layer 6, is scattered, scattering
Sound wave cross one another, cause mutual consumed energy, cause the sound of scattering to be unable to reach the energy of echo, also just play decrease
The reflex of sound, so as to reduce the reflection of the noise to in-car.Therefore, the resistance for auto sound that the present embodiment provides
Buddhist nun's glue can reduce in-car noise, improve riding comfort.
Specifically, the first damping layer 3 and the second damping layer 5 are butyl composite.Butyl damping is good, and will not
Volatilize pernicious gas, ensures the safety of occupant.Adhered layer is the compound environmentally friendly glue-line of butyl rubber, and its adhesive attachment is strong,
It is indeformable that metal plate position can be attached to for a long time, within the temperature range of-35-180 degree, stable performance.
The inner side of adhered layer 2 is additionally provided with gum paster 1.Adhered layer 2 can be protected before use by gum paster 1, prevented
The only surface nondestructive of adhered layer 2 or air-dried, causes sticky decline, is pasted not strongly.When damping glue is installed, gum paster 1 is opened,
Carry out sticking construction.
More specifically, protective layer 6 is aluminum foil plate.Aluminum foil plate light weight, easy processing, it can effectively reduce the entirety of damping glue
Weight.
Reference picture 3, the surface of aluminum foil plate are provided with embossing, form depressed part 62 and lug boss 61.By Sheet Metal Forming Technology to aluminium
The processing embossing of paper tinsel plate, so as to form the surface of bumps, processing technology is simple.
More specifically, the integral thickness of damping glue is more than or equal to 2 millimeters.According to the surface that studies for a long period of time, the thickness of damping glue
During less than 2 millimeters, soundproof effect is poor, is unsuitable for auto sound.
Embodiment two
The damping glue for auto sound that the present embodiment provides, is additionally provided with more between the first damping layer and the second damping layer
Hole noise reduction layer.Partial noise is absorbed by porous noise reduction layer, so as to improve soundproof effect.
